1.4 Code of Practice on Energy Labeling of Products  
 
Pursuant to Section 15 of the Energy Efficiency and Conservation (EEC) Act, the Code 
of Practice on Energy Labeling of Products (COPE) provides for the calculation 
methods of the following:  
 
1.4.1  The Display Monitors Energy Efficiency Rating in the DOE Energy Label is 
based and calculated as follows:  
 
EEF =  Luminous Area ( m2)
Energy Consumption (kWh) 
 
1.4.2  For the estimation of monthly energy kilowatt -hour (kWh) consumption 
(based on a specified hour of daily usage), as shown in the DOE Energy Label, 
the calculation is as follows:  
 
Monthly kWh Consumption = Power Consumption (kW) x Daily Operati ng 
Hours  x 30 days  
Where:  
 
Daily Operating Hours  are the assumed length of time that the equipment is 
operated in a day and is expressed in hours. With regards to the DOE Energy 
Label, this parameter is assumed to be six (6) hours.  
 
1.4.3  For the estimation of monthly electricity cost, the calculation is as follows:  
 
Monthly Electricity Cost = Monthly kWh Consumption x Electricity Price  
 
Where:  
 
Electricity Price  is the prevailing peso per kWh, as indicated in the electricity 
bill issued by an electric power distribution company.  
 
1.4.4  For the estimation of monthly Greenhouse Gas (GHG) emission due to monthly 
electricity consumption, the calculation is as follows:  
Monthly GHG emission = Monthly kWh Consumption x Emission Factor  
 
Where:  
 
Emission Factor  is the Simple Operating Margin (OM) Emission Factor 
derived using the power grid statistics and is available in the DOE Website.  
 
Note: The unit of the calculated GHG emission shall be in kg CO 2 per kWh . 
 
1.5 Minimum Energy Performance  
 
1.5.1  Display monitors  manufactured and assembled  outside the Philippines must 
meet the  MEP requirement of the  country of origin , as may be applicable.  
 
1.6 Standby Power Requirement  
 
1.6.1  The measured standby power shall be rounded off to the nearest 0.1 W and   
PELP – IMPLEMENTING GUIDELINES FOR DISPLAY MONITOR S                                             Page 4 of 10 
 shall not be more than 1.0 Watt . 
 
1.7 Tolerances  
 
The following tolerances shall apply:  
 
1.7.1  The measured standby power shall be rounded off to the nearest 0.1 W and 
shall not be more than 110% of the rated standby power of the test sample.  
 
1.7.2  The calculated EEF shall be rounded -off to the nearest 0.1 m2/kWh  and shall 
not be less than 90% of the rated EEF of the test sample.  
  
1.7.3  The measured energy consumption shall be rounded -off to the nearest 
0.001kWh and shall not be more than 110% of the rated energy consumption 
of the test sample.  
 
1.7.4  The measured viewing screen size shall be rounded -off to the nearest 1mm 
and shall not be less than 99% of the rated viewing screen size of the test 
sample .

 ANNEX A  
GUIDELINES ON DECISION RULE  
 
This document will provide the decision rule that will be used to account for measurement 
uncertainty, based on ILAC -G8:09/2019.  
 
 
Definition of Terms:  
 
Acceptance Interval  - interval of permissible measured quantity values.  
 
Acceptance Limit (AL)  - specified upper or lower bound of permissible measured 
quantity values.  
 
Guard Band (w)  – interval between a tolerance limit (TL) and a corresponding 
acceptance limit (AL) where length w = |TL – AL|. 
 
Measured Quantity  Value  - quantity value representing a measured result.  
 
Specific Risk - is the probability that an accepted item is non -conforming, or that a 
rejected item does conform. This risk is based on measurements of a single item.  
 
Tolerance  Interval / Specification Interval  - interval of permissible values of property.  
 
Tolerance Limit (TL) / Specification Limit - specified upper or lower bound of 
permissible values of a property.  
 
 
Decision Rule  
 
A Binary decision rule is when the result is limited to two choices (pass or fail). As explained 
below, the declaration of conformity is binary acceptance.  
 
 Binary Acceptance based on Guard Band  
 
 The decisions are based on guard banded acceptance limits. The acceptance limits, AL = TL 
– w, where U is the expanded measurement uncertainty or equivalent to w. The estimate of the 
measurand is assumed to have a normal probability  distribution and specific risk is used for the 
risk calculation. In this case, the risk of accepted items to  be outside the tolerance limit is less 
than or equal to 2.5%.  
 
 
 
  
 
 
 
 
 
 
 
 
 
 
 
 
 
PELP – IMPLEMENTING GUIDELINES FOR DISPLAY MONITOR S                                             Page 10 of 10 
  
 
 
 
 
 
 
 
 
Statements of Conformity are reported as follows:  
• Pass – acceptance based on guard band; the measurement result being below the 
acceptance limit, AL = TL – w.  
Fail – rejection based on guard band; if the measurement result is above the 
acceptance limit, AL = TL – w
